The faecal-oral group of diseases is transmitted by person-to-person contact, through water, food or directly to the mouth. The absence of a proper water supply, rubbish and dirty surroundings with an abundance of flies are the typical situations in which these diseases thrive. The incidence of these diseases can be controlled by: (i) breaking the faecal-oral cycle with personal hygiene; (ii) increase in water quantity; (iii) improvement in water quality; (iv) food hygiene; and (v) the provision of sanitation. The disposal of garbage and the control of flies are also important.
Many of the diseases in this group cause diarrhoea (Table 8.1).
